You will need to file for divorce and have a Qualified Domestic Relations Order entered along with the Judgment to get a share of your husband's 401k (half of what was accumulated during the marriage). An experienced attorney can help you with the process. If the expense of filing is prohibitive, you can seek out assistance from legal aid; if you are indigent, the court can suspend the filing fees or order your spouse to pay them. Also, you can file a motion to have your husband pay your attorney fees.
